Introduction to Anatomy Flashcards
Gross Anatomy
The study of body organs without aided eyes.
Embryology
The study of PREnatal (before birth) development of body organs.
Systemic Anatomy
System wide study.
Divide the body into different SYSTEMS depending on the FUNCTIONS of various organs.
Osteology
Study of BONES
Arthrology
or
Syndesmology
The study of JOINTS and LIGAMENTS
Myology
study of MUSCLES
Angiology
Study of organs of CIRCULATION like the HEART, BLOOD VESSELS, and LYMPHATICS
Splanchnology
study of SPLANCHNIC ORGANS that includes 3 body systems:
Respiratory system
Urogenital system
Digestive system
Neurology
study of the NERVOUS System
Esthesiology
study of SENSE organs
Anatomy is classified into three main branches
Gross Anatomy: body organs without aided eyes
Embryology: prenatal development of body organs
Histology: cells and tissues using a microscope
Two approaches to learning anatomy
SYSTEMIC
TOPOGRAPHIC
Systemic Anatomy
divide the body into different SYSTEMS depending on FUNCTION
Topographic Anatomy
LOCATION of body organs in relation to each other
Body Cavities
THORACIC cavity: lungs, heart, associated blood vessels
ABDOMINAL cavity: liver, spleen, stomach, intestines, pancreas, kidneys, ureters, ovaries etc.
PELVIC cavity: terminal parts of digestive system, rectum, urinary system, pelvic urethra, reproductive system, cervix
Osteology
study of BONES
Arthrology or Syndesmology
study of JOINTS and LIGAMENTS
Myology
study of MUSCLES
Angiology
study of organs of CIRCULATION like the heart, blood vessels and lymphatics
Splanchnology
study of SPLANCHNIC organs that include 3 body systems:
R respiratory system
U urogenital system
D digestive system
Neurology
study of NERVOUS system
Esthesiology
study of SENSE organs
Dermatology
study of SKIN and associated structures
Endocrinology
study of ENDOCRINE glands
Topographic Anatomy
study of LOCATION of body organs in relation to each other
Median plane
imaginary line passing through the body crania-caudally
dividing the body into two equal left and right halves
Topographical Planes
Median Plane
Sagittal Plane
Transverse Plane (cross section)
Frontal Plane (Horizontal Plane)
Sagittal plane
any plane PARALLEL to median plane
Transverse Plane (Cross section)
at a right angle to the median plane.
It divides the body into cranial and caudal parts
Frontal plane
Horizontal plane
at a right angle to both median and transverse planes,
dividing the body into dorsal and ventral parts
Topographical terms (location of body organs)
cranial
caudal
medial
lateral
dorsal
ventral
proximal
distal
palmar
volar
plantar
Cranial
more towards the head
‘the heart is cranial to diaphragm’
Caudal
more towards the tail
‘the diaphragm is positioned caudal to the heart’
Medial
closer to the median plane
Lateral
relatively away from the median plane
‘the lungs lie lateral to the heart’
Dorsal
more TOWARDS the backbone or vertebral column
‘the kidneys are located dorsal to the intestines.’
(used in reference to body organs)
Ventral
relatively AWAY from the vertebral column
‘the intestines are located ventral to the kidneys.
(used in reference to body organs)
Proximal
relatively CLOSE to the vertebral column.
(used in reference to bones of extremities)
Distal
away from the vertebral column.
(used in reference to bones of extremities)
Palmar / Volar
refers to the Caudal surface of the fore limb below the elbow joint
Plantar
refers to the Caudal surface of the hind limb below the hock joint
Body Cavities
T thoracic cavity
A abdominal cavity
P pelvic cavity
Thoracic cavity
lungs
